Which of the following is a common recommendation for contact lens hygiene?

Maintaining proper hygiene while handling contact lenses is crucial to prevent infections and ensure safe use. One of the most fundamental recommendations is to wash hands thoroughly before handling lenses. This practice removes dirt, oils, and microorganisms that could be transferred to the lenses and subsequently to the eyes, minimizing the risk of complications such as keratitis or conjunctivitis.

Thorough hand washing involves using soap and water and is particularly important before inserting or removing lenses. It's advised to dry hands with a lint-free towel to prevent any fibers from coming into contact with the lenses. This basic yet essential practice promotes overall eye safety and lens health.

In contrast, rinsing lenses with tap water can introduce harmful bacteria and pathogens, which is not safe. Similarly, using saliva to clean lenses is not recommended as it can transmit bacteria from the mouth to the lenses. Storing lenses in a warm environment is also discouraged, as excess heat can degrade lens material and promote microbial growth. Thus, washing hands thoroughly prior to lens handling stands out as the best and most vital practice for contact lens hygiene.
